The World
Record for the Longest Prehistoric Snake

While giant dinosaurs
roamed the earth, snakes were basically the same size as they are now.
The longest prehistoric snake was the python-like Giganthopis garstini,
which inhabited what is now Egypt about 38 million years ago. Parts of
a spinal column and a small piece of jaw discovered in Fayum, in the Western
Desert, indicate a probable length of some 11m (36ft|).
